Description
Neutrino and antineutrino interactions with two muons in the final state have been studied by the CCFR collaboration in the Fermilab Tevatron neutrino beam. The rate of neutrino- and antineutrino-induced prompt same-sign dimuon production in steel was measured using a sample of 220 μ-μ- events and 15 μ+μ+ events with Pμ>9 GeV/c, and energies between 30 GeV and 600 GeV. In addition, a sample of 5044 νμ and 1062 bar νμ induced opposite-sign (μminus-plusμ±) events was also observed with Pμ1≥9 GeV/c, Pμ2≥5 GeV/c, and 30≤Eθ≤600 GeV. The opposite-sign data support the slow rescaling model of charm production with a value of mc=1.31±0.24 GeV/c2. The CKM matrix element Vcd=0.209±0.012 and the nucleon strangeness content, ηs=0.064+0.0075-0.0065 are also extracted from the data. The first measurements of the Q2 dependence of the strange quark densities, xs(x), are also presented
